**"The Fire of Han Dynasty"**
Lu Mingyu, a double genius at Hua Xia University, was persecuted upon graduation and traveled through time with his unfinished scientific research ambitions to become Huo Qubing, a famous general in the Western Han Dynasty. When he woke up, he was being sent to Shuofang for killing Li Gan, and found that this young body had already contained chronic poison. Faced with the fate of premature death recorded in history books and the crisis of Xiongnu's oppression, he decided to rewrite history with modern knowledge.

When Lu Mingyu promoted gunpowder mass production and water conservancy reforms, he not only had to deal with the Huns' imitation iron warships, but also uncovered the traitors who had infiltrated the Gewuyuan - the tattoos on their ankles were exactly the same as the evidence of the poisoning case three years ago.
From the sulfur trap under the ice of the Weishui River to the explosion conspiracy of the dragon pillars in Weiyang Palace, from the suspected collapse of the Pinyang Iron Mine to the mysterious case of spontaneous combustion in the Baqiao Granary, a technological revolution spanning the north and south of the Great Wall will eventually detonate the most shocking civilizational transition in the cold weapon era. When the black gunpowder of the decisive battle in Mobei illuminates the grassland, the mercury vapor of the alchemy furnace in the deep palace...
